determine the best location for gluing. The distance is approx. 80mm from the canopy
opening. Use care to keep the horizontal servo board level.
Once the ideal position has been determined, tack-glue the unit in place (CA) prior to
permanently fixing with thickened Epoxy (cotton or kevlar pulp, milled fiberglass) followed by
a strip of fiberglass cloth (about 2cm wide) on both sides of the joint (top and bottom.
Smooth out the thickened Epoxy before it hardens.
The rudder/servo linkage is the "closed loop" type using two braided steel cables. Two
openings (left and right) must be plotted in the fuselage for the projected cable run, about
5cm forward of the rudder control-horns. Test fit the cables and rework the openings – if
needed – so that the cables do not rub.

The servos can be mounted once the glue has
dried/cured. The rudder servo is installed first,
with the output arm oriented toward the
fuselage bottom and fixed in place, as one of
the mounting screws will be partially blocked
by the (optional) tow release servo. Install the
tow release servo only AFTER this step, if

The complete unit is then guided into the
upper rear fuselage from the cockpit opening,
with the vertical servo board facing the front, to
